1TSB integration and migrationM&A & integrationIdentified$15M–$45M
The Banco Santander brief flags this opportunity: TSB integration and migration. Lead with a fixed-scope 3-week entry offer that proves value quickly, then grow it into integration management, conversion delivery and synergy tracking through to the last conversion.
From opportunity: TSB integration and migration
- Why now

Deal size$15M–$45M
Pursuit cost$235K
Win probability35%
Estimate: Estimate. Pursuit cost is about 47 person-weeks of account, sponsor and SME time at a blended $5,000 per person-week. The entry offer itself is a fixed fee of roughly $140k, or an Accenture investment if the pursuit is contested. The deal range is the 12-24 month follow-on (integration management, conversion delivery and synergy tracking through to the last conversion), scaled for an extra-large (G-SIB or global leader) client from a reference range of $15-45M. It is not based on client budget data. Win probability of 35% is a planning assumption for a Mega Diamond.
